The friction coefficient is a critical indicator to measure the braking effect of

. It is the ratio of the frictional force between two surfaces to the vertical force acting on one surface. For example, different grades of friction coefficients are suitable for different types of cars: EE grade is suitable for European and American cars, FF grade is an international standard, GG grade is for European models, and HH grade is for racing cars. However, the friction coefficient should be balanced as an excessive friction coefficient could affect the comfort of driving.

EE grade: 0.25-0.35

FF grade: 0.35-0.45

GG grade: 0.45-0.55

HH grade0.55-0.65

      link hidden, please login to view a very strong Automotive Aftermarket background and work experience in managing and running an organization similar to DMA. In his two years with our organization, Fred has comfortably assimilated into the DMA culture and exhibited thoughtful decision-making and leadership, while directly managing many of our key projects. He is now intimately knowledgeable about the workings of DMA, as he has been involved in most aspects of the business, extending beyond his direct responsibilities. I fully trust Fred’s ability to assess our business situations and make timely and deliberate decisions. He and I are fully aligned in the direction we steer the company and the effort it will take to achieve success. We both share a passion for serving the customer with a sense of urgency as our #1 priority. Fred’s areas of direct responsibility will remain the same as today: Supply Chain, Operations, Customer Service, Facility Management, and he will be assuming Product Management, and Engineering & Quality Management. This change of title acknowledges that Fred is assisting me in the overall day-to-day running of the company. It also represents that Fred is now my official backup for directing the company and making any required decisions in my absence. Fred also has full authority to sign on behalf of the company. 
      My role and responsibilities remain the same as CEO and Chairman of the Board. With the launching of our new joint venture factory SDI in Thailand and other corporate travel obligations, it was clear that the time had come when DMA needed someone officially in charge when I am unavailable. This evolutionary organizational step assures the stability and consistency that positions DMA to continue to be a fast-acting and customer-responsive company with clear lines of leadership and communication for our employees. 
      I am confident that this change is another positive milestone in the development of DMA. Please join me in congratulating Fred on this well-deserved appointment.”

      Various Types of Bearing Brake Disc(source from :rdbrake.com)
      The primary function of bearing brake discs is to provide a stable and reliable surface for the brake pads to grip, thereby facilitating effective braking. When the brake pedal is pressed, the brake pads clamp onto the spinning brake disc, generating friction that slows down the wheel's rotation. The bearings within the brake disc assembly ensure smooth and consistent rotation, minimizing wear and tear on the braking system.
      Types of Bearing Brake Discs
      Ventilated Brake Discs: These discs feature internal vanes or vents that allow air to circulate, dissipating heat more efficiently. They are commonly used in high-performance vehicles and heavy-duty applications where heat management is crucial.
      Solid Brake Discs: These are simple, flat discs without internal vents. They are typically used in smaller or lighter vehicles where excessive heat build-up is less of a concern.
      Drilled and Slotted Discs: These discs have holes and grooves that enhance heat dissipation and improve braking performance, especially under extreme conditions. They also help in expelling dust and debris from the braking surface.
      Composite Brake Discs: Made from a combination of materials such as cast iron and carbon composites, these discs offer superior performance, reduced weight, and enhanced heat resistance. They are often found in high-end sports cars and racing applications.
      Maintenance of Bearing Brake Discs

      Regular maintenance of bearing brake discs is essential to ensure the longevity and reliability of the braking system. Key maintenance practices include:
      Inspection: Regularly inspect the brake discs for signs of wear, such as grooves, cracks, or uneven surfaces. This can prevent potential brake failure.
      Cleaning: Keep the brake discs clean from dust, dirt, and debris. Use appropriate cleaning solutions and tools to avoid damaging the surface.
      Lubrication: Ensure that the bearings are properly lubricated to reduce friction and prevent overheating. Use the recommended type and amount of lubricant for optimal performance.
      Replacement: Replace the brake discs when they show significant signs of wear or when they reach the manufacturer's recommended lifespan. Timely replacement can prevent more severe damage to the braking system.

      Various Packaging way of Brake Discs( from RDBRAKE.COM)
      In the automotive parts industry, as the key safety components, the packaging design of brake discs is not only related to the product's market image, but also directly affects consumers' purchasing decisions.
      1. Plastic bag
            Generally, brake discs are first packed in a plastic bag. The plastic bag will be sealed as customers' requirement.

      2.  Neutral white box and kraft paper box: low cost.
